The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollen moves from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower through pollination. This transfer can occur via wind, insects, birds, or other pollinators. Successful pollination leads to fertilization and the formation of seeds.
Pollination
A bee transfers pollen from the anther to a stigma by visiting flowers to collect nectar and pollen as food. While foraging, pollen grains stick to the bee's body due to static electricity and the hairy texture of their bodies. When the bee moves to another flower, some of this pollen is brushed off onto the stigma, facilitating cross-pollination, which is crucial for plant reproduction. This process enhances genetic diversity in plants and promotes healthy ecosystems.
A bee is attracted to a flower from color, sweet nectar, etc... As the bee sucks up the nectar, pollen from the anther(s) gets stuck on the bee's body fur. When the bee moves on to the next flower, some pollen that was stuck to the bee from previous flowers falls off onto the stigma of the new flower.
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA

Anther pollen refers to the pollen grains produced by the anther, which is the male reproductive organ of a flower. These pollen grains contain the male gametes needed for fertilization when they land on the stigma of a flower.

in angiosperms, some flowers (like garden peas) self-fertilize or underdo self-fertilization or "selfing" because it ensures that a seed will develop. The only thing is, selfing means no genetic variablity is possible... and life is boring that way.... haha! its not that^ its called self polinating`

Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.
Bees are attracted to flowers by their bright colours and their desire to collect nectar. Nectar tends to be found close to the base of the petals and as the bee attempts to reach it the bee brushes against the male stamens of the flower, which deposit pollen on to its fur. When the bee flies to another flower the same process occurs and some of the pollen which was already present on its fur may brush against the female parts of this flower and then serve to fertilise it.

Pollen
Insects typically pollinate flowers as they move from plant to plant searching for food. Many flowers produce nectar, a sugary liquid that many insects eat. When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs. Perhaps the most well-known pollinator insects are bees and butterflies, but wasps, moths, flies and beetles can be pollinators as well.
